Plasma beta-hexosaminidase isoenzymes A and B exhibit different relations to blood glucose levels in a population of Type 1 diabetic patients

The activity of lysosomal enzymes, such as beta-hexosaminidase (Hex), is increased in the plasma and serum of diabetic patients. A positive association has been shown between enzyme activity and glycated proteins, indicating an association with the degree of metabolic control. Several isoenzymes of Hex exist. Studies have reported different proportions of the isoenzymes in plasma from diabetic pat

Skeletal muscle fatigue and endurance in young and old men and women

The effects of increasing age on skeletal muscle fatigue and endurance were assessed in 22 healthy young (14 men and 8 women; mean age, 28 +/- 6 years) and 16 healthy old (8 men and 8 women; mean age, 73 +/- 3 years) individuals. All subjects performed 100 repeated maximum dynamic knee extensions at 90 degrees.s-1 (1.57 rad.s-1) using an isokinetic dynamometer (Cybex II). Peak torque was recorded

Skeingeborg : borgen som Saxo glömde

The castle Skeingeborg built around 1200 by the archbishop in Lund. It was build octagonal as a roadstation in the desert forestland at the border between Denmark and Sweden at the route between the bishopries in Lund and Växjö. The ironproduction and logistic possibilities in the area is discussed together with comparing studies of castles, roads and inland water transports in Denmark-Sweden

Systematic Synthesis of Substituted Phosphido-bridged Osmium Clusters

The labilised clusters [Os3(CO)11–nLn(NCMe)][n= 1, L = PMe3 or CNBut; n= 2, L = P(OMe)3] have been prepared. The reaction of [Os3(CO)11 –nLn(NCMe)] or [Os3(CO)10{P(OMe)3}(NCMe)] with either [Os3(CO)11(PH3)] or [Os3(µ-H)(CO)10(µ-PH2)] led to the formation of the phosphide-bridged clusters [Os6(µ-H)(CO)21{P(OMe)3}(µ-PH2)], [Os6(µ-H)(CO)21(PMe3)(µ-PH2)], [Os6(µ-H)(CO)21(CNBut)(µ-PH2)], [Os6(µ-H)(CO)2

Mutation analysis of the NSD1 gene in patients with autism spectrum disorders and macrocephaly

Background: Sotos syndrome is an overgrowth syndrome characterized by macrocephaly, advanced bone age, characteristic facial features, and learning disabilities, caused by mutations or deletions of the NSD1 gene, located at 5q35. Sotos syndrome has been described in a number of patients with autism spectrum disorders, suggesting that NSD1 could be involved in other cases of autism and macrocephaly

Lifetime of the isomeric O-2(+) state in Be-12

Mean lifetime tau of the isomeric O-2(+) state in Be-12 has been determined by measuring decay spectra of delayed y-rays from stopped Be-12 2 nuclei produced by the projectile fragmentation of O-18 at 100 A MeV. A consistent value of tau = 331 +/- 12 ns was obtained from the time spectra of the E2 gamma decay to the 2(1)(+) state and the positron annihilation following the E0 decay to the ground s

Brain lesion contrast in MR imaging. Dependence on field strength and concentration of gadodiamide injection in patients and phantoms

PURPOSE: To compare the contrast effects of gadodiamide injection at 0.3 and at 1.5 T, at different concentrations in phantoms, and to correlate the results to clinical doses used for examining brain lesions. MATERIAL AND METHODS: Gel phantoms with T1 and T2 corresponding to brain gray matter were doped with different concentrations of gadodiamide injection and examined with T1-weighted sequences.

Ectomycorrhizal colonisation of roots and ash granules in a spruce forest treated with granulated wood ash

Granulated wood ash has been proposed as a slow release fertiliser suitable for forest soils. In this study ectomycorrhizal colonisation of roots and ash granules was studied in a 40-year-old spruce forest treated with 0, 3 or 6 t ha(-1) granulated wood ash. We used PCR-RFLP methods for ITS-typing and identification of ectomycorrhizal fungi. In total 20 different ITS-types were recognised on roots

Structure and mobility in water plasticized poly(ethylene oxide)

The change in structure and mobility of poly(ethylene oxide) (PEO) containing 2 wt% of fumed silica and the water self-diffusion coefficient in concentrated PEO-water systems have been investigated at room temperature in the water weight fraction, w(w) range 0-0.50 w/w. Pulsed field gradient nuclear magnetic resonance was used to measure the self-diffusion coefficients. Structure and mobility prop

Formation mechanism of mesoporous silica formed with triblock copolymers; effect of salt addition

SBA-15 was synthesised with Pluronic P104 ((EO)(27)-(PO)(61)-(EO)(27))) its Structure promoter at 45 degrees C, with and without NaCl (1.0 M) added to the Synthesis Mixture. TEOS (tetraethyl orthosilicate) was used as silica source. The formation process was studied by in-situ SAXS/SAXD using synchrotron light. Addition of salt affects the micellar size, initial cell-parameter of the 2-D hexagonal

Convergence of implicit finite difference methods applied to nonlinear mixed systems

A new technique to prove convergence of finite difference methods applied to nonlinear PDEs arising in computational fluid dynamics is presented. The underlying systems may be hyperbolic, parabolic or of mixed type like the Navier-Stokes equations. Implicit finite difference methods are analyzed. The essential idea leading to success is the introduction of a pilot function that is highly attractiv
